摘要: Accelerating parameters of beam-driven wakefield acceleration in an extremely dense plasma column has been analyzed with the dynamic framed particle-in-cell simulator, and compared analytic calculations. In model, a witness beam undergoes TeV/m scale alternating potential gradient excited by micro-bunched drive 1025 m−3 1.6 × 1028 m−3 column. The gradient, energy gain, transformer ratio have extensively studied quasi-linear, linear-, blowout-regimes. simulation analysis indicated that system hollow channel offers ∼20% higher enlarging radius (r) from 0.2 λp to 0.6 blowout regime. This paper suggests feasibility crystalline structure (e.g., nanotubes) high electron density.
